Out-of-pocket costs on medicines in 2009
• Total sales of prescription drugs 152 Meur
• Health Insurance covered 88 Meur (58%)
• Patient co-payment 63 Meur (42%)
• 75% are used by persons 65+ (retired/pension)
• In 2009 there were 360 000 on retired persons
• Average retired person (pensioner) spent 1 month income in 2009 to cover co-payment of reimbursed prescription medicines

Opportunity costs (alternative cost)
• The loss of potential gain from other alternatives when one alternative is chosen
• The "cost" incurred by not enjoying the benefit that would be had by taking the second best choice available
• Opportunity costs are not restricted to monetary or financial costs, but real value, lost time or any other benefit that provides utility should also be considered opportunity costs.
"Time is Money“, Benjamin Franklin (1706–1790)

Simvastatin „saved“ 72 lives, i.e. protected 3% of patients, but 182 died despite they took simvastatin
NNT = 31; 31 patients have to take simvastatin for 5 years in order to prevent 1 death

Medicalization
• Is the process by which human conditions and problems come to be defined and treated as medical conditions, and thus become the subject of medical study, diagnosis, prevention or treatment
• Can be driven by new evidence or hypotheses about conditions; by changing social attitudes or economic considerations; or by the development of new medications or treatments.
19
Overmedicalization
• Overmedicalization is altering the meaning or understanding of experiences, so that human problems are re-interpreted as medical problems requiring medical treatment, witout net benefit to patients or citizens
• Birth and death of a human being is certified by medical doctors, who declare the start and end of a bilogical body and legal entity
• Alcohol overuse and drug addiction were for centuries a moral and individual problem, then became legal problems, and now are medical problems to be solved by dedicated medical services
20
Overdetection
• A health related finding is detected in an (asymptomatic) person by a testing technology
• Finding indicates something that is temporary or would have regressed
• Physicians reflexively respond to receiving positive tests by ordering more tests
• Examples – ultrasound screening of thyroid has tripled the incidence (diagnosis and treatment) of thyroid cancer in thirty years, but the death rate has remained the same.
• Hypertension – from 160/100 to 140/90, but white-collar hypertension in 20-25% persons
21
Overdiagnosis
• Diagnosis drives treatment
• An (asymptomatic) person is diagnosed with a condition, which does not produce symptoms or death or net benefit for the person, wasting resources while increasing patient anxiety.
• Examples – benign breast tumor detected via mammographic screening
• Reasons – use of technology to justify its expense; defensive medicine
22
Expanded definitions and disease mongering
• Creating diseases out of behaviour or feelings that are within normal human experience, and promoting those diseases to the public to enourage use of health services, especially tests and medicines (Carter 2015, BMJ 350:h869)
• ADHD – Attention deficit hyperactivity disorder • PMDD – premenstrual dysphoric disorder –
medicalization of normal human function and behavior, when antidepressant fluoxetine (also known as Prozac) was being repackaged as a PMDD therapy under the trade name of Sarafem
23
Willingness to pay
• Willingness to pay (WTP) is the maximum amount an individual is willing to sacrifice to gain utility (benefit) or avoid something undesirable
• WTP is usually constrained by individual's wealth
• But in a welfare state WTP for:
– hospital care
– public health
– prescription-only medicines
– chemotherapy in oncology

Ipilimumab
• One of the first drugs to demonstrate efficacy in metastatic melanoma
• Hazard ratio for death 0.68
• Median overall survival with ipilimumab 10 months vs 6.4 months with standard therapy
• Alive after 2 years 20% vs 10% (health gain 1/10)
• Annual treatment cost USD 125,000
• UK NICE estimate 55,000–70,000£ per QALY
27
Fear of death
• Fear of death treated as something that can be fixed with biotechnology rather than something requiring existential wisdom or common sense
• Examples – the idea of aging and dying as medical illnesses effectively "medicalized" human life and left individuals and societies less able to deal with these "natural" processes
28
Supplier induced demand & Price elasticity
• Supplier induced demand – the amount of demand that exists beyond if the patients are fully informed
• Price elasticity of demand gives the percentage change in quantity demanded in response to a one percent change in price
• Price elasticities are almost always negative
• In health care it can be positive
– da Vinci Surgical System
– „innovative“ pharmaceuticals
– Biotech products in oncology

We can afford new treatments
• If we have more money for health care
• If we learn to stop uneffective treatments and disinvest uneffective technologies
• If we discontinue drugs, which have no effect, instead of adding new ones

The desire to take medicine is perhaps the greatest feature which distinguishes man
from animals
(sir William Osler 1849–1919)
founder of Johns Hopkins School of Medicine (Baltimore, US);
established the first residency program for specialty training
of physicians;
he was the first to bring medical students out of the lecture hall for bedside clinical training
created the 1st formal journal club at McGill University

Conclusions
• Medicine is an uncertain practice and may be harmful
• Attending harms is as important as attending the benefits
• The harms are not limited to physical injury, but include social, psychological and economical side-effects, that are not so easy to capture
Less is more
